Reduce the proportion of people with severe hemophilia who have more than 4 joint bleeds each year — BDBS‑01

Hemophilia is a chronic bleeding disorder linked to high costs from hospitalizations, outpatient visits, treatments, and missed work and school. Joint bleeds are the leading cause of disability in people with hemophilia, and people with more joint bleeds are more likely to have joint damage. Preventive treatment can decrease joint bleeds and lower the risk of joint damage in young boys with severe hemophilia.
